[0032] See also Figures 1 to 7 As shown, the utility model provides a bottle blowing machine aligning device with low embryo return rate, Figure 1 This is a structural schematic diagram of the bottle blowing machine's alignment device fixedly installed on the frame, including an alignment component 100, which is arranged from high to low from the input end to the output end. The alignment component 100 includes a first side panel 1 and a second side panel 2 that are relatively arranged, and an alignment area and a rejection area are formed between the first side panel 1 and the second side panel 2 in the direction from the input end to the output end; the alignment area is installed with at least one straight embryo block unit 3, and the rejection area is sequentially installed with a first oblique embryo block unit 4 and a second oblique embryo block unit 5, and the inclination directions of the first oblique embryo block unit 4 and the second oblique embryo block unit 5 are opposite. The straight embryo blocking unit 3 is used to block the initially unaligned bottle preforms to prevent excessive unaligned bottle preforms from being transported forward and causing the preforms to be stuck; the first oblique embryo blocking unit 4 and the second oblique embryo blocking unit 5 cooperate to push the unaligned bottle preforms transported to the downstream of the alignment component 100 to the sides and drop them into the embryo return hopper 9 for embryo return. The first oblique embryo blocking unit 4 and the second oblique embryo blocking unit 5 are inclined in opposite directions, and can thus push unaligned bottle preforms at any angle into the embryo return hopper 9.

[0033] The bottle blowing machine alignment device of the present invention can block most of the bottle preforms into the preform gap 24 and successfully align them by successively arranging a straight preform blocking unit 3, a first oblique preform blocking unit 4 and a second oblique preform blocking unit 5 between the first side plate 1 and the second side plate 2, thereby reducing the probability of preforms returning and improving the efficiency of bottle preform alignment.

[0034] In this utility model, as shown in the attached Figure 2-4 As shown, the preform straightening and blocking unit 3 includes a straightening and rotating rod 31 and a straightening and rotating baffle 32. The ends of the straightening and rotating rod 31 are rotatably connected to the first side panel 1 and the second side panel 2, respectively.

[0036] In the present invention, a first slanted baffle 61 is formed at the bottom of the alignment area of ​​the first side panel 1, and a second slanted baffle 62 is formed at the bottom of the alignment area of ​​the second side panel 2. The first slanted baffle 61 is inclined toward the second side panel 2, while the second slanted baffle 62 is inclined toward the first side panel 1. The minimum spacing between the first and second slanted baffles 61, 62 is greater than the preform clearance 24. The first side panel 1, the first slanted baffle 61, the second slanted baffle 62, and the second side panel 2 enclose a temporary storage area for unaligned preforms.

Unaligned preforms are then transported forward to find opportunities for alignment. There is no inclined baffle in the rejection area. There is a gap between the first roller 11 and the first side plate 1, and the gap is connected to the embryo return hopper 9. There is a gap between the second roller 15 and the second side plate 2, and the gap is connected to the embryo return hopper 9, so that the unaligned preforms fall into the embryo return hopper 9.

The preform sweeping assembly comprises a rotary motor 71, a preform sweeping plate, and a preform sweeping cover plate 72. The rotary motor 71 is fixedly mounted to the first side panel 1, and the preform sweeping plate is mounted between the first side panel 1 and the second side panel 2. The rotary motor 71 drives the preform sweeping plate to rotate, sweeping the preforms back to the second inclined preform retaining unit 5 and then into the preform return hopper 9. The preform sweeping cover plate 72 covers the preform sweeping plate and prevents the preforms from falling out.

[0038] In the present invention, a feeding hopper 8 is fixedly installed at the input end of the alignment zone, and an embryo return hopper 9 is installed at the bottom of the rejection zone.

The first embryo-entering roller assembly 200 and the second embryo-entering roller assembly 300 are fixedly mounted on the left and right sides of the base assembly 400, respectively. A embryo-passing gap 24 is formed between the first embryo-entering roller assembly 200 and the second embryo-entering roller assembly 300 for the bottle body of the preform to be inserted into. The alignment assembly 100 is fixedly mounted on the top of the first embryo-entering roller assembly 200 and the second embryo-entering roller assembly 300. The drive assembly 500 is fixedly mounted on one end of the base assembly 400 for driving the first embryo-entering roller assembly 200 and the second embryo-entering roller assembly 300 to rotate. The rollers of the first embryo-entering roller assembly 200 and the second embryo-entering roller assembly 300 rotate in opposite directions. The preforms fall into the alignment assembly 100. The first and second preform-feeding roller assemblies 200 and 300 rotate continuously to allow the disordered preforms to fall into the preform-passing gap 24. Since the alignment assembly 100 is arranged from high to low from the input end to the output end, the preforms can be slowly aligned and conveyed forward.

[0040] In the present invention, the first embryo entry roller assembly 200 includes a first embryo entry frame 10, a first roller 11, and a first receiving component 12; the active end and the driven end of the first roller 11 are respectively rotatably connected to the first embryo entry frame 10, and a first sprocket 13 is fixedly sleeved on the active end; the first receiving component 12 is fixedly installed on the output end of the first embryo entry frame 10.

The first adjustment bolt 123 passes through the first adjustment slot 124 to lock the first embryo guide inclined member 121 and the first bending inclined plate 1222. The first bending inclined plate 1222 serves to position and support the first embryo guide inclined member 121. The design of the first adjustment slot 124 allows for fine-tuning of the connection surface between the first embryo guide inclined member 121 and the first bending inclined plate 1222, thereby adjusting the spacing between the first embryo guide inclined member 121 and the second embryo guide inclined member to accommodate preforms of varying outer diameters.

[0042] In the present invention, the second embryo entry roller assembly 300 includes a second embryo entry frame 14, a second roller 15, and a second receiving member 16. The active and passive ends of the second roller 15 are rotatably connected to the second embryo entry frame 14, and a second sprocket 17 is fixedly mounted on the active end. The second receiving member 16 is fixedly mounted on the output end of the second embryo entry frame 14.

The second adjustment bolt passes through the second adjustment slot to lock the second embryo guide inclined member and the second bending inclined plate. The second bending inclined plate serves to position and support the second embryo guide inclined member. By designing the second adjustment slot, the connection surface between the second embryo guide ramp and the second bending ramp can be fine-tuned, thereby adjusting the distance between the second embryo guide ramp and the first embryo guide ramp 121 to accommodate preforms with different outer diameters.

[0043] In the present invention, the distance between the first roller 11 and the second roller 15 constitutes a preform gap 24 for the preform to pass through.

[0044] In the present invention, the drive assembly 500 includes a motor 18, a motor sprocket 19, a driven sprocket set 20, and a chain (not shown); the motor 18 is fixedly mounted on the outside of the first embryo entry frame 10, the motor sprocket 19 is fixedly assembled at the output end of the motor 18, the driven sprocket set 20 is fixedly mounted on the outside of the second embryo entry frame 14, and the driven sprocket set 20 includes a first driven sprocket 201 and a second driven sprocket 202. The motor sprocket 19, the first sprocket 13, and the first driven sprocket 201 are connected by a chain transmission, and the second sprocket 17 and the second driven sprocket 202 are meshed and connected. The motor 18 drives the motor sprocket 19 to rotate, driving the chain, the first sprocket 13, the first driven sprocket 201, and the second driven sprocket 202 to rotate synchronously. The second sprocket 17 meshes with the second driven sprocket 202, so that its rotation direction is opposite to that of the first sprocket 13.

[0045] In the present invention, the drive assembly 500 also includes an idler assembly 21 that is removably mounted on the outside of the first embryo entry frame 10. The idler assembly 21 includes a mounting plate 211, a third adjustment bolt 212, and an idler assembly 213.

The idler assembly 213 is vertically mounted on the mounting plate 211 and engages with the chain. By moving the mounting plate 211 up and down, the idler assembly 213 adjusts the chain tension. The idler assembly 211 cooperates with the spacing adjustment assembly 600 to adjust the embryo gap 24. When the embryo gap 24 needs to be increased, the idler assembly 21 moves downward to reduce the chain tension. When the embryo gap 24 needs to be decreased, the idler assembly 21 moves upward to increase the chain tension.

[0046] In the present invention, the bottle blowing machine alignment device also includes a spacing assembly 600, which includes a spacing fixing block 22 and a spacing bolt 23. The spacing fixing block 22 is fixedly mounted on the base assembly 400, and the spacing fixing block 22 is threadedly connected to the second embryo-feeding roller assembly 300 via the spacing bolt 23. By rotating the spacing bolt 23, the second embryo-feeding roller assembly 300 moves laterally, thereby adjusting the size of the embryo-passing gap 24.
